SPECIFICATION forming part of Letters Patent No. 490,478, dated January24, 1893.

Application tiled March 8. 1892. Serial No. 424,159. (No model.)

To @ZZ whom it may concern.-

Be it known that I, CHARLES ADAM CHRIS- TIAN KORETKE, a citizen of theUnited States of America, residing at Belvidere, in the county of Booneand State of Illinois, have invented certain new and useful Improvementsin Heating-Stoves, of which the following is a specification, referencebeing had therein to the accompanying drawings.

Io This invention relates to certain new and useful improvements inheating stoves of that class in which hot air Iiues or pipes areprovided to increase the heating capacity of the stove, and it has forits objects among others I5 to provide a stove of this character inwhich the heating capacity will be greatlyincreased Without materiallyadding to the cost of the stove. I form the lire-pot practically all ofpipes or lues, the bottom being an annular zo flue, the top a similarpipe or Hue and the side Walls being vertical iiues connecting andcommunicating with the said top and bottom. An annular flue is alsoprovided near the top of the stove and with this upper iiue commu- 2 5nication is established from the fire pot fines.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claim.

3o The invention is clearly illustrated in the accompanying drawings,Which, with the letters of reference marked thereon, form a part of thisspecification and in which Figure l is a central vertical sectionthrough astove provided with myimprovements. Fig. 2 is a horizontalsection on the line zz of Fig. l, looking down-ward.

Like letters of reference indicate like parts in both views.

4o Referring now to the details of the drawings by letter, A designatesthe base of the stove and A the legs. Above the ash pit and ash door isthesurrounding flue or pipe B rectangular in cross section and formingthe bottom of the fire-pot.

C are airinlet pipes passing upward through the bottom of the stove andcommunicating with the flue B. The ring B forms the support for thegrate and the vertical walls of the lire-pot are formed by a pluralityof ver- 5o tical Iiues D. The vertical flues may all cornmunicate withthe ring B and with the surrounding flue or ring E arranged about mid-Way the height of the stove and which forms the upper part of thefire-pot. These flues being arranged upon all sides of the fire-pot theair will be quickly heated and from the upper iiue or ring E it isconducted to the annular flue or ring F at the top of the cylinder andfrom thence out into the room 6o through a suitable outlet or outlets,as seen atfin Fig. 1. By this construction and arrangement of parts thestove as Well as all the nues from the bottom of the ash pit will bereadily heated and this without additional coal. Soft or hard coal orother fuel may be employed. 4

The outer portion of the grate has an out- Wardly-extending flange a asseen in Fig. l

which rests upon the tube B which is made 7ol rectangular in crosssection for this purpose.

What I claim as new is;-

The combination with the lower surrounding tube B rectangular in crosssection, of the grate having outwardly-extending flange a resting uponsaid tube, the surrounding I'lue E about midway of the height of thestove, the vertical ilues D connecting the flues B and E and forming thesides of the tire-pot, the upper surrounding iiue F, the side iiues con-8o nectingthe same with the flue E, and the air inlet fines C passed upthrough the bottom ot the stove and communicating with the iiue B, allsubstantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES ADAM CHRISTIAN KORETKE.
